Hello,
I'm using a HSDIO 6541 with LabWindows, drivers version 1.5.1.
I noticed that when I configure the DATA_POSITION attribute on my GENERATION session, if I choose RISING_EDGE, the data is actually still on FALLING_EDGE and changes on RISING_EDGE, and if I choose FALLING_EDGE, data is still on RISING_EDGE etc...
This doesn't happen on Acquisition session, the sampling surely happens as defined by the attribute.
So the attribute DATA_POSITION seems to be inverted, only on generation sessions.
